Although non-removable batteries are already common in our mobiles, in their day we cried out to heaven for not being able to change this hardware component easily and ourselves. The official control of the substitution has been limited to the official Technical Services, or to those third parties specialized in repair. For many years, the main Samsung phones have not had a removable battery, but that does not mean that when the time comes, we can not change it ourselves.
The process to change the battery in our Samsung Galaxy is not as simple as it might seem. Repair experts often highlight how difficult it is to take off the back of Korean terminals, so you have to be very sure before deciding to take the step . However, with a little tomorrow, patience, and following the instructions step by step, we can achieve it ourselves.
what you need to know
Precisely, the non-removable battery model was carried out by the manufacturers to have control of the repairs and minimize those devices that, being under warranty, were damaged by the manipulation of the users themselves. You have to know that Samsung makes it very clear in its policy of exclusion of guarantees. That is, if your mobile is not two years old and a problem arises during this process, you may have problems trying to enforce the warranty. The point of the Samsung policy where it clarifies it with precision expressly says: “Breakage of any of the seals of the case or battery cells, or obvious signs of tampering in them”
Furthermore, before starting the process it is recommended that the current battery level is below 25% . Otherwise, there could be a risk of a termination event, in case the battery is damaged during the repair.
How to change the battery of the Galaxy Note
The Galaxy Note have been considered difficult to repair for several generations. The back cover of the Galaxy Note 8, Note 9, Note 10 and Note 20, comes strongly attached and we will need to perform several steps before being able to access the battery to remove it correctly. Let’s see the steps one by one and that are common to the series:
- The first mandatory step is to heat the edges of the device for at least one minute. This can be done with a special tool, heat gun or hair dryer, always being careful not to overheat the phone.
- Now we will have to insert an opening pick, for which we will need the rear panel to lift slightly thanks to the heat applied, using a suction cup. When lifting with force a gap will be made between the casing that we will have to take advantage of to insert the spike.
- Now we must slide the pick along the edge of the device without inserting it further in than necessary to avoid damaging the interior. In this way, we can cut the glue and gradually introduce more spikes to open more of the housing surface.
- Once all the sides are open, we will have to lift the rear panel and use a screwdriver to remove the screws from the wireless charging coil
- We will use pliers to lift and flip the metal shield that covers the battery connector
- We hold the metal shield and lift the battery connector to disconnect it.
- We remove the connect of the wireless charging coil from the motherboard
- We take off the wireless charging coil as it is attached with a small adhesive and we proceed to remove it
- The next step is to use a screwdriver to remove the 4mm screws holding the daughterboard cover and use tweezers to remove it
- We disconnect the primary and secondary key from the motherboard, as well as the primary and secondary cable from the daughterboard
- The next step is to disconnect the display cable connector from the motherboard
- Now we will have to loosen the adhesive from the battery, applying drops of isopopyl alcohol through the slits to soften the adhesive and be able to remove the battery.
- The suction cup must be used again to lift the battery and separate it from the frame. If it is difficult, you can try adding more drops of alcohol.
- Then the pick is inserted into the gap created between the battery and the frame and we pull to extract the battery
Galaxy Note 8
With this veteran but very capable even in 2020, we will have no problem finding custom kits to proceed with battery replacement. This kit available on Amazon costs less than 20 euros and has everything you need, including of course the suction cup, the tines and the replacement 3,300 mah battery.
Galaxy Note 9
Similarly, we will have a kit for less than 20 euros to proceed with the replacement of the 4,000 mAh battery of the Galaxy Note 9. As in the previous case, the product is certified by CE / RoHS by accredited, qualified testing laboratories and accredited, being 100% compatible as the original battery.
Galaxy Note 10 and Note 10 Plus
At Amazon we find a battery kit + tools to replace the battery of the Galaxy Note 10, whose price is slightly over 20 euros. Not so for the Galaxy Note 10 Plus, where we do find its replacement battery in Amazon , but whose tools will have to be purchased separately if we do not have them.
Galaxy Note 20 Family
As is often the case with newer terminals, the battery kits for Samsung’s newer terminals have not yet been released. However, any problem that may arise with the battery of these devices is still covered by the official guarantee, so it makes less sense that we are going to venture ourselves in its replacement, being able to request free of charge, the repair by the technical service of Samsung
How to change the battery of the Galaxy S
It was starting with the Galaxy S6, when Samsung began to introduce non-removable batteries in this family. Since then, the steps to get to the battery are very similar, with the difference of finding ourselves before or not with the wireless charging coil in the event that our terminal is compatible. Therefore, the Galaxy
- As before, the first mandatory step is to heat the edges of the device for at least one minute, using a heat gun or a hair dryer, always taking care not to overheat the phone.
- Then we insert an opening pick, for which we will need the rear panel to lift slightly thanks to the heat applied, using a suction cup. We will do this until a hole is made between the housing that we will have to take advantage of to insert the pick.
- As we saw before, we will have to slide the pick along the edge of the device without inserting it further in than necessary to avoid damaging the interior. In this way, we can cut the glue and gradually introduce more spikes to open more of the housing surface.
- The next step leads us to remove the wireless charging coil. As we say, if your terminal does not have this capacity, you can skip the step, since you will be closer to the battery.,
- The coil is easily removed, as it is connected to the rest of the terminal by spring contacts.
- Now we can lift the battery using a spudger type lever or similar.
- We will use a screwdriver to remove the 4mm long screws that fix the speaker and the lower frame and remove it.
- We can now lift and remove the main and auxiliary flexible cables of the daughter panel
- The next step is to remove the flex and main cables from the motherboard
- Now we will remove the main cable from the motherboard
- We apply isopropyl alcohol in the gaps between the frame and the edges of the battery, tilting the mobile to help its penetration and to better soften the adhesive.
- We put the suction cup in the center of the battery holding the upper and lower part of the mobile and pull hard upwards.
- When removing the battery we must remove the remains of glue and apply the new adhesive when we replace the new battery.
Galaxy S6
There is no problem finding replacement battery kits for the Galaxy S6 and Galaxy S6 Edge . Although these terminals continue to function correctly, your battery may have required some replacement or other. The price for the 2,750 mAh battery kit for the Galaxy S6 is 15 euros , while the kit with the 2,700 mAh for the Edge variant is available for 22.90 euros.

This means that the battery could be problematic in some cases, depending on how the device was used. Luckily there are kits for the Galaxy S10 trio. We found a kit for the standard Galaxy S10 for 25 euros. Cheaper we find the kit for the Galaxy S10 +, which costs 16.56 euros , while the kit for the S10e has a price on Amazon of 24.85 euros.

How to change the battery of the Galaxy A
There is no doubt that we are facing more modest terminals than the previous ones, but that they offer some advantages. Cheaper materials such as plastic tend to predominate and have fewer technologies. This facilitates access to the battery in the terminals of the Galaxy A family.
- The first step is to use an eject tool to remove the SIM card tray
- Now we will have to use an opening peak between the screen and the cover, from the bottom of the charging port
- When sliding the pick, we will notice how the clips that anchor the lid to the device open
- We will repeat the steps with all the corners and edges of the device until all the plastic clips are released and we can remove the back cover
- We remove the 3mm phillips screws to remove the motherboard
- We now use a spudger or pry bar to lift the cover off the motherboard and release the plastic clips that hold it in place.
- Now we will use the lever again to disconnect the battery, lifting the connector from its socket
- Once done we can disconnect the interconnection and the flexible cables of the screen from the motherboard
- We remove the 3mm screws and remove the cover of the daughter board
- We remove the interconnection cable by lifting the connector from its socket
- We apply heat to the screen to loosen the glue that is under the battery, for at least two minutes
- We move the screen cable away from the battery so that it can come out correctly
- We insert a credit card or similar under the battery and slide underneath to finish peeling off the adhesive
- Once the battery is done it will come out and we can place the new one, retracing our steps.
Galaxy A Family
Samsung sells or marketed to date more than 25 terminals of the Galaxy A family, which it constantly renews. Kits to be able to replace the battery will depend a lot on the model and the time in the market that they have. We can always take a look at Amazon by introducing our model followed by the words “drum kits” or take a look at pages like ifixit that sell reliable kits, although today they do not have for the Galaxy A.
